Not one of the three had looked at a clock at Ballyshiel.

“Do you remember anything about coming home again?”

They did not. They looked furtively at one another and presently broke into a grin.

“Ah! I see how that was,” Hewitt said good-humouredly. “That’s all now, I think. Come, it’s ten shillings each, I think.” And he handed over the money. The men touched their forelocks again, stowed away the money and prepared to depart. As they went Larry Shanahan stepped mysteriously back again and said in a whisper, “Maybe the jintlemen wud like me to kiss the book on ut? An’ as to the toime—”

“Oh, no, thank you,” Hewitt laughed. “We take your word for it, Mr. Shanahan.” And Mr. Shanahan pulled his forelock again and vanished.

“There’s nothing but confusion to be got from them,” Mr. Bowyer remarked testily. “It’s a mere waste of time.”

“No, no, not a waste of time,” Hewitt replied, “nor a waste of money. One thing is made pretty plain. That is that the shot was fired on Tuesday. Mrs. Hurley never noticed the report, but these three men were close by, and there is no doubt that they heard it. It’s the only single thing they agree about at all. They contradict one another over everything else, but they agree completely in that. Of course I wish we could have got the exact time; but that can’t be helped. As it is it is rather fortunate that they disagreed so entirely. Two of them are certainly wrong, and perhaps all three. In any case it wouldn’t have been safe to trust to mere computation of time by three men just beginning to get drunk, who had no particular reason for remembering. But if by any chance they had agreed on the time we might have been led into a wrong track altogether by taking the thing as fact. But a gunshot is not such a doubtful thing. When three independent witnesses hear a gunshot together there can be little doubt that a shot has been fired. Now I think you’d better sit down. Perhaps you can find something to read. I’m about to make a very minute examination of this place, and it will probably bore you if you’ve nothing else to do.”

But Mr. Bowyer would think of nothing but the business in hand. “I don’t understand that window,” he said, shaking his finger towards it as he spoke. “Not at all. Why should Main want to get in and out by a window? He wasn’t a stranger.”

Hewitt began a most careful inspection of the whole surface of floor, ceiling, walls and furniture of the sitting-room. At the fireplace he stooped and lifted with great care a few sheets of charred paper from the grate. These he put on the window-ledge. “Will you just bring over that little screen,” he asked, “to keep the draught from this burnt paper? Thank you. It looks like letter paper, and thick letter paper, since the ashes are very little broken. The weather has been fine, and there has been no fire in that grate for a long time. These papers have been carefully burned with a match or a candle.”

“Ah! perhaps the letters poor young Rewse was writing in the morning. But what can they tell us?”
